{Specification of Letters Patent.

Application filed June 24, 1914. Serial No. 846,908.

To all whom it may concern Be it known that l, GHAnLns S. Srnnn- MAN, a citizen of the United States, residing at Glendale, county of Los Angeles, State of California, have invented a new and use ful Eyeglass-Stud, of which the following is a specification.

My object is to make a stud for rlmless eyeglasses which may be applied to the lens comparatively loose and then ad u stably tightened so as to avoid the liability of breaking the lens; and my invention consists of the novel features herein shown, described and claimed.

Figure 1 is a front elevation of a set of rimless eyeglasses embodying the principles of my invention. Fig. 2 is a fragmentary sectional detail upon an enlarged scale on the line 2-2 of Fig. 1, this detail showing the connection of the nose bridge stud to the lens. Fig. 3 is a fragmentary sectional detail upon an enlarged scale upon the line 3-3 of Fig. 1, showing the temple end piece stud connected to the lens. Fig. 4: 1s a sectional detail on the line H of F 1g. 2. Fig. 5 is an enlarged fragmentary top plan view showing a finger piece mounting connected to the lens, the view being taken as indicated by the arrow 5 in Fig. 6. Fig 6 is a sectional detail on the line 66 of Fig. 5. Fig. 7 is a perspective of the adjustable shoe. Fig. 8 is a perspective of the ad usting screw.

The adjusting shoe 1 has a connectlon side 2 to fit the edge 3 of the lens 4 and has a central perforation 5 at right angles to the connection face 2. The adjusting screw 6 has a screw-threaded portion 7, there being a screwdriver head 8 upon one end of the screw-threaded portion 7 and a reduced pintle 9 upon the other end.

In applying the principles of my invention to a riding bow bridge 10, as shown in Figs. 1, 2 and 4:, a screw-threaded opening 11 is formed through the base of the spacing block 12 which connects the straps 13 and 14: and the screw 6 is mounted in this screw-threaded opening 11, said opening 11 being counter-bored at the outer end to receive the head 8 and the adjusting shoe 1 is placed between the straps 13 and 14 with the pintle 9 in the opening 5. The opening 5 is counter-bored from the face 2, and the end of the pintle 9 is upset in the counter bore so as to hold the shoe in place upon the pintle, between the straps 13 and 14:. The adjusting screw 6 is withdrawn to the limit, bringing the shoe back against the face of the base 12. Then the lens 1 is inserted between the straps 13 and let and the screw 15 is inserted through the straps and through the lens. Then the adjusting screw 6 is manipulated to place the desired pressure of the adjusting shoe 1 against the edge of the lens 4:. The shoe 1 will rock sulliciently upon the pintle 9 to allow the face 2 to ad just itself to the edge of the lens and apply equal pressure to the lens throughout the length of the shoe. In applying the adj ustable shoe to a temple end piece, as shown in Figs. 1 and 3, the temple arm 16 is offset relative to the base 17 so as to provide room for the adjusting screw 6. In applying the adjusting screw to a finger piece mounting, as shown in Figs. 5 and 6, the nose bridge 18 is offset relative to the base 19 so as to provide for inserting the adjusting screw 6.

In actual practice I have found it very diflicult to apply the studs heretofore in use rigidly to the rimless lenses without danger of breaking the lenses. Tn applying my studs this dii'liculty is avoided because the studs are first applied comparatively loose and afterward adjusted to fit under the desired tension.

The details of construction may be varied in many ways without departing from the spirit of my invention as set up in the following claims.

I claim- 1. In an eyeglass stud, a base; straps eX- tending rigidly from the base and adapted to receive a'lenshetween the straps; a'pivot place and so as to adjust the shoe against inserted through the straps and adapted. for the edge of a lens.

insertion through the lens a shoe loosely n mounted betweenthe straps against the CHARLES STELLMAN' v 3 5 base; and a screw screW-seated through the 'W itnesses: V 7 base and having a pintle extending through BERTHA MoMAsTER,

- V the shoe and-upset so as to holcitheshoe in JOSEPH HILL.
